In this study, the behavior of the “T Type” non-circular tunnels undergone
to seismic effects was studied in closed differential equations and in
numerical methods, and the comparative
results were presented. A non-circular tunnel liner was considered in soft
and weathered rock materials and in soft soil ground media and analyses were
executed. According to the suitable solutions, the results of the analyses were
found compatible, and the results of the numerical analyses for the non-linear
behavior of the materials undergone to earthquake loads, under above mentioned
surrounding ground conditions, were found more consistent compared with the
solutions based on elastic material behavior such as Simplified Deformation
Analysis, Free Field Shear Strain Approach, Simplified Frame Method and
Pseude-statics Analysis.
